Core Components for the Build

The ASRock DeskMeet X600 is the centerpiece of this compact gaming PC. This barebone system includes a small yet versatile case, a motherboard and a 500W 80+ Gold power supply unit (PSU). Its design is optimized for high-performance components while maintaining a minimal footprint. To complete the build, you’ll need the following components:

• CPU: AMD Ryzen 9700X, an AM5 processor with a 65W TDP, offering a strong balance between performance and energy efficiency.
• RAM: 32GB of Patriot DDR5 RAM, making sure smooth multitasking and optimal gaming performance.
• CPU Cooler: Thermaride EXP90X47, a compact cooler designed to fit within the DeskMeet X600’s limited space while providing efficient thermal management.
• GPU: PowerColor 960 XT Reaper, a high-performance graphics card that fits within the 200mm GPU length restriction of the case.
• Storage: Lexar One Tig EQ790 SSD with an integrated heatsink, offering fast load times and improved thermal performance.
• Wi-Fi Card: A compact Wi-Fi card to ensure reliable wireless connectivity.

These components are carefully chosen to maximize performance while adhering to the space and power constraints of the ASRock DeskMeet X600.

Step-by-Step Assembly

Building a compact gaming PC requires precision and attention to detail due to the limited space available. Follow these steps to assemble your system efficiently:

• Begin by removing the default mounting brackets inside the DeskMeet X600 case to create space for your components.
• Install the AMD Ryzen 9700X CPU onto the motherboard, making sure proper alignment. Secure the Thermaride EXP90X47 cooler on top of the CPU for effective heat dissipation.
• Insert the 32GB Patriot DDR5 RAM into the designated memory slots. This capacity ensures smooth performance for modern games and multitasking.
• Install the Lexar One Tig EQ790 SSD into the M.2 slot. Its integrated heatsink helps manage temperatures during extended gaming sessions.
• Connect the PowerColor 960 XT Reaper GPU to the PCIe slot, making sure it fits within the 200mm length limit of the case.
• Attach the compact Wi-Fi card to the motherboard to enable wireless connectivity.
• Carefully connect the non-modular PSU cables to the motherboard, CPU and GPU, making sure all connections are secure and properly routed to maintain airflow.

Take your time during assembly to avoid damaging components and to ensure proper cable management, which is crucial in a compact build.
